WGISS
• WGISS = Working Group on
Information Systems and Services
– Work includes
•
•
•
•
Archive Task Team
Data Services Task Team
International Directory Network
....
Archive Task Team
• Responsible for promoting and
encouraging exchange and
communication of archive and records
management best practices between
the members of WGISS.
ATT Activities
• Current Topics
–
–
–
–
Long-Term Archive Strategies or Policies
Archive Media, Data Formats
Storage/Backup Strategies
Digital Data Preservation or Recovery.
• Future topics may include
–

–
–
–
Agency Presentations on Data Migrations
Environmental Storage Standards
Copyright Issues
Physical Security Standards
Old Equipment Inventory
Analog/Film Data Preservation or Recovery.
Data Services Task Team
• Serves as a forum for exchange of technical
information about WWW / Internet related
software technologies of interest to the CEOS
community, including web services in general
and web mapping services (such as those
based on OGC specifications) in particular.
DSTT Activities
• IDN Services
• Product Visualizations Through Web
Service Chaining
• ECHO Web Services
• Services for Agricultural Application
International Directory Network
Task Team
• Responsible for coordinating activities among
the nodes to maintain, improve, and expand
the functions and use of the IDN.
– Based on Global Change Master Directory work at
NASA
• Enables users to locate and obtain access to Earth
science data sets and services relevant to the global
change and Earth science research. The GCMD
database holds more than 17,000 descriptions of Earth
science data sets and services covering all aspects of
Earth and environmental sciences.
IDN TT Activities
• Portal Development
• Service Enhancement
• Metadata Development (DIF and SERF)
– Directory Interchange Format
– Service Entry Resource Format
Group on Earth Observations
• Ministerial level entity housed at World
Meteorological Organization offices in
Geneva
–

–
–
69 member countries
46 participating organizations
4 committees
1 working group
96 tasks.......
GEOSS
• ...to produce the Global Earth Observation
System of Systems
– Coordinated, comprehensive, sustained system of
existing systems
– Emphasis on respecting/preserving existing
needs/agreements, use of international standards
– System of systems architecture is critical to
success of GEOSS [as is ‘project management’
approach]
Activities
• Centered around the 96 tasks
– 1/3 for Architecture and Data
– 2/3 scattered between the other 4 areas
– All based on some need to disseminate or
manipulate data for one or more societal
benefit areas.
• Tasks cover many/all aspects of eGY

CEOS and GEO
• CEOS is being recognized as the satellite arm of
GEO
– Has put forward a Virtual Constellation task
• The Task has the purpose to advocate rapid development of
the “CEOS Constellations Concept”. Observations from a
virtual constellation would provide better temporal, spatial, and
spectral resolution and related data management and
dissemination. A series of virtual constellations are in definition
by space agencies, in consultation with user communities
within the CEOS framework, each being designed to address a
significant implementation challenge, and each addressing key
GEOSS observation gaps in the process.
Proposed Virtual Constellations
• The CEOS Constellation for Precipitation, which aims to
strengthen international cooperation on space-based
observations of precipitation, including realization of the GPM
mission (AR-06-10) and providing guidance to new;
• The CEOS Constellation for Land-Surface Imaging, designed
to ensure the relevant synergy with High Resolution
Multispectral Imager Continuity (AR-06-09);
• The CEOS Constellation for Ocean Surface Topography,
designed to ensure continuity of Sea Level measurement in
accordance with GCOS requirements (CL-06-02);
• The CEOS Constellation for Atmospheric Chemistry, which
will address many of the needs for atmospheric observations of
the climate community (CL-06-02);
WGISS and GEO
• WGISS has done an assessment of its
work with respect to GEO tasks to
identify possible areas for contribution.
– Lots of possibility in the IDN area and in
the Projects and Applications Subgroup
